It's Fun to Play the Piano ... Please Pass It On!

I recently bought a casio px 350 and been playing on it for a weeks and a few days ago I noticed that some of they keys don't sound right. I made a video on it that shows the problem, mostly it's the key third from the right that sounds the worst and it sound more in reality then on the video.

I have the same issue before. At least one white key has a click sound. And one white key has much louder bang sound than other key. This is usually not a issue if you turn the volume of speakers / headphone up.

I've owned a number of Privias'. The keys start loosening up and banging more as the keyboard ages. It might be just one now. I tend to agree with the opinions that counsel accepting it. You could exchanged it now, but what you're experiencing, well, there's no telling what the next one will be like.

Don't get me wrong. That sound would bug me too and I'd probably try a replacement. My new Yamaha U1 actually has some noise on a couple of keys I want checked out during its first tuning. However, FWIW, it's interesting some (louder) key noise is a feature while other key noise is a nuisance.

same issue here with my Casio PX150 after about 2-3 weeks of playing. I had a post on this last week. For me it's one key so far, but it seems like other keys may start doing this as well.

Here's a sample of what mine sounds like... seems very similar : PX 150 Key noise

This appears to be more widespread than I thought, I've seen several people mention it. There was a comment on my youtube video with a user experiencing the same issue. I bought the keyboard online, so I would need to ship it to a repair center or Casio to get fixed. But I'm not confident that the issue will stay away.

I researched a LONG time before settling on the Casio, and this kind of key noise was never mentioned with the 130/ 330 models. Could this actually be a defect with the new action in the '50 models?

Seems like I have to return it, feeling abit bummed because I ordered it online so I will probably be out of a piano for a while...

@Radian Is it really a widespread problem? seems like that would suck getting a new one and that having problems aswell. I like you researched for a couple of months before I decided on this.. I really hope I won't come to regret it.

Well it was more a rhetorical question than anything. It's hard to say how widespread this is, that's something only Casio knows.

However I've now seen several people with the same problem, so it's not a fluke.

Some of the comments are along the line of `oh well you bought a cheap piano, so expect it to fail`. I'm not sure I agree with that. Casio is a long-established brand, and the previous models seem to last a long time (years). When I buy a $600 keyboard I expect it to maintain its functionality for a long time. Keys that start audibly `clicking` after only several weeks of play is really not acceptable. If I bought a cheaper car like a Kia I would still expect to be able to roll up the windows properly even 5 years from now

...and this kind of key noise was never mentioned with the 130/ 330 models....

It was mentioned plenty, but the reports eventually died down. It was soon noticed that there was more rehashing someone else's report than the problem was common. The rush to fear here is hilarious. Smiss has been inconvenienced, that is all.

To emenelton's point, just about every older dp I come across from any brand does have a few keys that make a different noise than their neighbors. Rarely does the noise affect the mechanism, but it's bound to happen one day.

Ah well, Yeah I kinda agree with what you're saying I don't think it's acceptable that one of the keys starts to sound like this after just a short while. With headphones on it's not a problem but even with the volume turned up without headphones I can hear the click from that key.

Cheap is a relative term but for me this is by no means a cheap keyboard. I tested all the keys when I got it and they all made the same sound now a total of 3 keys are making a click noise, though only the one to the right is being loud enough to be distracting.

This is a known issue and complaint with Casio Privias. My opinion is it is caused by the felt compressing. Casio uses a soft material for dampening. Casio should consider using woven wool felt-the kind used in acoustic pianos. It is still a good product, but I agree, noisy keybeds are annoying.

My Kawai ES6 has a little plasticy clicking on most of it's keys, nothing like the Privias' I've owned.To keep it real though, my Privia's all retained their functionality, no key ever stop working. It was more like a car that developed rattling but it's windows still continued working.

-I've had the px-150 for a couple of months now (same action, I believe). I really like the feel of the keyboard, if anything, it's grown on me but I'm not yet convinced of its robustness. I can already hear a couple of keys that don't sound quite like the others although they're not yet exhibiting a gremlin quite as distinct as in your video.

Only time will tell how these actions bear up against the strain. In the meantime, I'll resist the temptation to return the piano for servicing until close to the expiry of warranty or when glitchy noises become truly unbearable/affect too many keys - whichever is the sooner.

Part of a known problem online comes from people passing along talk of the problem which in and of itself makes it known. The attention a problem receives online does not make the problem widespread. It only makes talk of the problem widespread. How many individual cases involving any Casio model have been talked about by the owners?

I have seen a few instances with the 150/350 models mentioned online. I don't recall there being more than 10 and I think it is closer to 5 individual cases and at least two didn't like the replacement they received (one of those being a member here). Just what that actually represents out of all 150/350s sold we cannot determine unless we have knowledge that only Casio could have.

Who is it that knows of this issue? Has Casio acknowledged it as a known issue? Which Privias? What percentage are bad vs. good? What data from which source(s) lead to this conclusion? When a company acknowledges a problem as a "known issue" it usually starts with an official statement that is followed by an update or a recall/fix campaign.

Often people reading and repeating what they see online make things out to be more than they truly are. Saying something like "this is a known issue with..." lends substance to an idea that may not warrant it. It is known to those who read piano forum posts. A few cases have been mentioned online but there are probably many more people talking about a few cases than there are cases warranting characterizations that encourage a certain perception of the problem.

In this instance I think a better choice of words would be "there have been a few cases of _____ reported online ragarding _____" then leave it to the reader to draw their own conclusions rather than "this is a known issue" which can mean something with huge implications and repercussions.

The statement I made was not directed at just the PX-X50 series. There have been complaints about noisy keys on Privias dating back to the earliest models going back to 2003. The issue is not exclusive to Casio as all manufacturers get complaints about noisy keys, and all do repair the issue under warranty to satisfy their customers, including Casio.

Understood, regarding models. I only brought up the PX150/350 because those are what I have focused on:

OCD is complaining about the slightly different gaps between the keys, or the very slight difference between the resting height of the keys. What you've got there is not OCD material, it's defective. =( We know they can make a keyboard that doesn't go crunch crunch crunch.

i just saw this post, i know it is ancient but i have the px150 and after a while i had the same problem, i took it apart and found out that the sensor board that the contact strips are connected to is held to the main frame of the action with metal screws. Some of the screws get loose from playing, or maybe they aren't tight enough from the factory and so the board ends up rattling. If you (carefully) tighten the screws it completely fixes the problem and you have a quiet key again!
